This invention relates to presses for W001 and the like whereby the latter may be compressed into bales in a rectangular box-like body by means of a compressing head or monkey to which downward pressure is applied by mechanical means.

In presses of this type various means have been adopted so that in the upward position of the monkey, the latter may be moved sideways to give free access to the body of the press when placing the pressing operation, but such known constructions doinot give easy access or are usually provided with pressure applying means comprising a system of pulleys and a cable wound upon a winch drum, the cable being required to be slackened before swinging the monkey clear of the body. Furthermore, the cables owing to such slackness often require to be replaced upon the usual pulleys before a further compressing movement of the monkey can be made.

An object of the present invention is to provide improved pressure applying means for a press which will permit, in a box body type of press, free access to the body for loading and one which is free from the above disadvantages, is simple and quick in operation, and is not costly to manufacture compared with the more complicated types of presses already upon the market.

The present inventionin. common with mostwool presses of this type has a box-like body with sides, front and rear, capable of being opened out when it is desired to withdraw the compressed bale from the body. The box-like body rests upon a base board and is open at the top.

Above the open top a monkey or compressor is mounted upon a vertical member and is forced down upon the wool by a system of pulleys, and a cable capable of being wound upon a Winch rum.

The monkey is rotatably mounted upon the lower end of the vertical member and the latter is slidable in a crosshead which may be mounted upon two vertical supports disposed close to the respective sides of the body, the supports being preferably relatively movable with respect to the sides. The object in rotatably mounting the monkey with respect to the vertical member is to enable the monkey to assume a position in acwool in the bodyprior to each comcordance with any slight irregularity in the packing of the wool into the press body during the filling operation. It will be appreciated that the monkey and the vertical member are capable of movement relatively to the crosshead.

Accordin to thepresent invention, the crosshead, which extends across the top of the body of the press, is attached to the upper end of the said vertical supports, and may consist of two members between which the vertical member carrying the monkey is freely movable, in an up and down manner, but the said crossheadmay be made in one piece if provision is made for the vertical member to move vertically in relation thereto V when power is applied to the said member. 7 p

The means for applying power to the vertical member and the monkey carried thereby, comprises a system of pulleys and a cable, capable of being wound upon a suitable winch drum. The system of pulleys may be varied slightly but it consists essentially of two pulley wheels mounted centrally at the upper end of, the vertical member, one above the other,-and a pulley wheel carried upon the crosshead, near one end thereof. The arrangement of the pulleys is such that when a downward pull is exerted upon the vertical member the thrust is taken upon the crosshead at a point as near the vertical supports as is practicable. The cable for applying the downward pressure to the vertical member is anchored atone end, passes over the lower pulley wheel of the vertical'member, round the pulley wheel on the crosshead, over the second pulley wheel on the said member and thence to a winding drum round which 7 it'is coiled when the drum is turned.

' V In order that the invention may be more readaccompanying drawings wherein:

ily understood reference will n ow be made to the Figurel isa front elevation of pressure applying means in present invention. I V

.Figure 2 is aside view thereof.

Figures is adetail view of part of the rear of the press on annenlarged scale, illustrating the means for applying downward pressure to the monkey and forraisingthe latter clear oi the top of the'body. i

a press having accordance with the Figure 4 is a plan view, of the construction illustrated in Figure 1.

The body illustrated is of box-like formation, having a base it, sides Hi and ll, front i2 and rear i3, held together by long pins 14 passed through strappings l of angle iron which overlap at the corners. The respective sides, front and rear, it to l3, inclusive, are supported upon a base iii and the front i2 and side it are capable of being opened out about the pins M to remove the bale after moving the press locking clamp bracket 9 to the unlocked position. The press locking clamp bracket 1 and 2 of the drawings comprises a vertical bar pivotally mounted to the angle brackets it on one side of the press body and adapted to slip over the ends of the {angle brackets 85 on the front of the press body. When this locking clamp 9 is pivoted by swinging it to the left of the position shown in Fig. angle irons l5 on the front as viewed in-Fig. l are free so that the front of the press body may be pivoted about the pin i l to open the body for removal of the bale.

The top of the box-like body is open to receive the material to be compressed and above the open top a monkey I1 is positioned in such manner that it may be moved up and down, as desired, with relation to the body.

The press is provided with a crosshead l8 supported above the top of the body and through the said crosshead a vertical member it is capable of being moved by the means provided for applying downward pressure to the monkey H, said monkey ll being pivotally mounted as indicated at it upon the lower end of the said vertical member [9.

As illustrated the crosshead i8 is formed in two parts, see Figure 4, between which the member 19 carrying the in such manner that it the crosshead is secured to supports such as 2!).

The detailed construction of the supports 26 which are pivoted to the base it by pivot pin is are disclosed in my co-pending application, Serial No. 620,385 filed concurrently with the instant To retain the supports 26 in the in the drawings there fastened to the press application. operative position shown are provided catches 4| ing therein the latching ends of the respective pawls d2 pivotally mounted on arms at which in turn are supported on the supports The pawls 42 are capable of being withdrawn from the catches M by tie rods which may be lifted by crank arms 41 defined on the respective ends of a transverse rod 48 having a crank handle 49. The crank handle 49 is also used to pull the cross head !8 and monkey l1 clear of the body of the press when the box-like body is made ready to receive therein material to be compressed. As best shown in Figs. 2 and 4 of the drawings, a pair of somewhat U-shaped guide brackets are provided with one leg of each of the Us bolted to an associated one of the angle irons l5 and the other legs connected to the associated latches 4!. These brackets are adapted to receive and support in the bight of the U thesupports 20 when the crosshead and monkey assembly are to be supported clear of the press opening to allow wool to be placed in the said body. At One end of the crosshead a winch 2| is mounted and at the other end there is a ,pulley 22 freely mounted. The verticalmember l9 at or near its upper end has two pulleys 23 and 2d 1' of the drawings, the

to the crosshead by a ratchet face or art. .A crank. handle body and having notched out portions for receivthat Various ge and freely mounted one below the other. A cable 25 r for applying a downward force to the monkey I1 is secured at one end to the crosshead is by means of a shackle pin 26 which is bolted to the said crosshead l8. After leaving the shackle 26, the cable 25 passes over the lower pulley 23, then round the crosshead pulley 22, over the upper pulley 22, on the vertical member l9, and is secured to the drum of the winch 2! in known manner.

The winch: 2 I 'has a ratchet wheel 2'! capable of being engaged by an operating handle 28, which upon the shaft 29 of The handle 28 has a suitable pin, not shown, for engaging the teeth of the ratchet wheel 21 in a conventional manner well understood by those skilled in the 30 is mounted upon the shaft 29 to enable the winch 2| to be turned independently .of the handle 28; a ratchet pawl 38 is alsoprovided.

A pawl 3| is pivoted to the crosshead l3 and is adapted to engage a ratchet plate 32 set into the vertical member IQ for the purpose of safely rethe winch 2 i taining the said member-in its elevated position abovethe body of the press until it is desired that the monkey H be lowered.

For the purpose of raising the monkey after pressure has been applied by the winch 2!, cable 25 and system of pulleys 22, 23 and 24, a second v inch 33 having a crank handle 3% is mounted the crosshead l8 and receives a cable 35 which passes beneath a pulley 3B freely mounted upon the lower end of the vertical member is just above the monkey lLsaid cable 35 being secured in 31 about which the pawl iii is also pivoted.

The pulley arrangement upon the vertical member as and the crosshead I8 is such that the thrust on the said crosshead is widely distributed and that applied to the monkey is directly vertical.

When raising the monkeyll by means of the second winch drum 33 it is necessary to see that the main winch drum 2| is free to rotate in an anti-clockwise directionas viewed in Fig. 3 of the drawings.

While there has been shown and described a particular embodiment of the present invention it will be apparent to those skilled in the art modifications can be made without departingfrom the invention in its broader aspects, and it is therefore aimed in the appended claim to cover all such changes and modifications as fall within the true spirit and scope of the invention.
